Die casting is the most commonly used casting technology in the casting industry. There are various problems in die casting. These are the ten common problems in die casting: 1.Hammerhead Stuck In order to avoid the hammer head stuck, you can start from two aspects: 1. In production, the temperature is often measured to avoid the hammer head and cylinder temperature is too high to cause the hammer head stuck; 2. The use of materials should choose high-quality alloy materials to avoid the infiltration of impurities. When putting back materials, attention should also be paid to not letting impurities mix,…

Four Ways 3D Printing Could Make Traditional Manufacturing Obsolete
Imagine a world where everything is printable: a world without any shortage. This may seem impossible, but with the development of 3D printing technology, this vision may come true sometime in the future. I’m sure we’re no strangers to the concept of 3D printing by now; 3D printing and its 3D printing technology have been around since the 1980s. To some extent it seems that 3D printing is still the more expensive technology.

Which method is more cost-effective, such as prototype 3D printing or CNC processing?
During prototype proofing, some products can be made either by CNC processing or by 3D printing. Because CNC processing is relatively complicated and the workload is larger than 3D printing in theory, most customers take it for granted that CNC processing is more expensive than 3D printing. Is this the case? Li Gong, the professional master of precision models, introduced the differences between the two processing methods in detail According to Li, CNC processes need to be programmed and disassembled. Generally, a CNC machine needs 3-4 people, which means a large labor cost. Therefore, the cost of CNC mainly depends…

The microstructure morphology and distribution characteristics of defect bands in die casting magnesium alloy were studied, and the corresponding relationships between defect bands and pressure chamber precrystallization (ESCs), air shrinkage hole and die casting process parameters were established. On this basis, the formation and evolution mechanism of defect bands were discussed. The results show that the cross section solidification microstructure of die cast magnesium alloy can be divided into three regions with obvious differences in microstructure characteristics. With the increase of the low speed, the ESCs content in the solidification microstructure of die casting magnesium alloy gradually decreases, and the…
What are the advantages of CNC processing in rapid prototyping?

How was the military quick prototyping model process made at the air show?
The various military equipment we saw on the air show are actually military equipment models produced by the prototype factory, also known as the prototype. According to the requirements, some of these prototypes will be scaled down according to the prototype in size, but the appearance and structure are basically the same as the prototype, and have some functions of the prototype. Some equipment can also be directly assembled into a real military equipment prototype for operation testing. Why do military equipment need to be modeled? Instead of directly producing products? To understand this problem, we must first understand the…

Why 3D printing is one of the best manufacturing processes available today
Before, many manufacturers were designing with the help of CNC machining etc. Nowadays, many manufacturers are already doing it through 3D printing. 3D printing is one of the best manufacturing processes today, and why is it so, because it has some advantages that traditional manufacturing cannot give. Freedom of design Thanks to the layered construction method and the simple removal of supports, it is possible to create very complex shapes that cannot be produced by traditional methods. In fact, sometimes the support structure is not even needed, depending entirely on the complexity of the product being created. However, in general,…

The birth of 3D printing materials in the construction industry
Everything has its two sides and its advantages and disadvantages, and 3D printing is no exception. A very common disadvantage of 3D printing is that the strength of the parts produced by it is not as strong as those produced by traditional manufacturing. However, with the continuous progress of 3D printing materials and technology, 3D printing parts also show their unique strength and durability, which are equal to and even surpass traditional manufacturing. Now researchers at the University of Wisconsin Madison in Madison, the capital of Wisconsin, have developed 3D printing materials that are much stronger than other materials used…
